Hi Carol, I did not know if you meant a 9x13 pan or a 15x10 pan or larger. I am assuming a 15x10 jelly roll pan you mean.

Pumpkin Spice Bars
Makes 2 dozen
Preparation time: 10 minutes
Baking time: 30 to 35 minutes

1 package (18.25 ounces) plain spice cake mix
4 tablespoons butter, melted
1 large egg
1 package (8 ounces) cream cheese, softened
1 can (14 ounces) sweetened condensed milk
1 can (15 ounces) pumpkin
2 large eggs
1 cup chopped pecans or walnuts for topping

1. Place a rack in the center of the oven, and preheat the oven to 350 degrees. Grease a jelly-roll or half sheet pan about 18- by 13- inches and 1-inch deep. Place the cake mix, melted butter, and eggs in a large bowl and blend with a wooden spoon until they just come together. The mixture will be dry. Press this mixture over the bottom of the pan. Set the pan aside.

2. Place the soft cream cheese in a mixing bowl and blend on low until softened, 30 seconds. Add the sweetened condensed milk, pumpkin, and eggs. Blend until the mixture is smooth. Pour this over the crust, and top with pecans. Place the pan in the oven. Bake until the filling has set, 30 to 35 minutes. Cool 1 hour in the pan, then cut into bars.

Tip: Add a pinch of cinnamon or pumpkin pie spice to the cream cheese mixture. Make sure the cream cheese is soft before you begin.
